SM25JZ51,Bi-Directional Triode Thyristor,TO-247-3

The SM25JZ51 is a bi-directional triode thyristor (Triac) developed by Toshiba, designed for AC power control applications such as motor control, industrial automation, and temperature regulation. It features a 600V repetitive peak off-state voltage (VDRM) and a 25A RMS on-state current, ensuring powerful and stable operation under demanding loads.

With a low gate trigger voltage of 1.5V and a trigger current of 30mA, the SM25JZ51 offers sensitive and efficient switching capabilities. It is capable of handling high inrush currents, with an ITSM rating of 253A at 60Hz, making it ideal for industrial applications where surge currents are common.

The TO-247-3 package provides exceptional thermal performance and durability, making it suitable for high-power industrial and commercial applications. Its high dv/dt capability (300V/µs) ensures superior noise immunity and improved system stability in AC switching environments.
